Modern strength training of youth Dietmar Schmidtbleicher
Age and gender related training
Strength training with children 1. Fast increase in all strength components is possible 2. Increasing the strength performance capabilities increases the performance in a lot of sports and disciplines 3. Improvement in skills enhance the motivation 4. A given level of strength often is a prerequisite to fullfill the demands of a skill (for example: hurdles)
Strength training with children 5. A given level of strength can avoid frustration by diminuishing the number of unsuccessful attempts 6. As a consequence the training process is more effective 7. Strength training can reduce the risk of injury 8. Strength training can reduce the risk of orthopedical weakness
Structure
Structure and components of strength (2012) MOTOR ABILITY STRENGTH POWER STRENGTH ENDURANCE COMPONENTS MAXIMAL STRENGTH RATE OF FORCE DEVELOPMENT FATIGUABILITY
Physiology of strength
Structure and components of strength (2012) Morphological and physiological factors Nervous System - recruitment - frequency - synchronisation - reduction of inhibitation - reflexivity Muscle System - cross sectional area - fiber composition - fiber hypertrophy - metabolic capacity - elasticity of muscle and tendon
Classification of training methods
Maximal contractions Adaptations Load intensity 90 100% Muscle mass + Repetitions 1 3 Utilisation of muscle potential +++ Sets 3 Force maximum ++ Rest intervall 5 min Rate of force development +++ contraction speed explosiv Preactivation ++ Number of workouts per week 2 3 Reflex activity duration of the period 6 8
Submaximal contractions Adaptations Load intensity 70 75% Muscle mass +++ Repetitions 8 12 Utilisation of muscle potential + Sets 5 Force maximum +++ Rest intervall 2-3 min Rate of force development + contraction speed slow to rapid Preactivation + Number of workouts per week 2 3 Reflex activity duration of the period 10-12
